An idea for control points.

What if the Troll in Nightshade Pass gains skill and hit points during a fight, and keeps them as long as it lives. Kind of like the way a control point spawn increases, except that if it dies it will revert back, and the new-spawned Troll will be a nuber.
The more people in the fight, and the longer they fight, the bigger the pot gets. As the Troll gets closer to death, and tougher, unanticipated kills for both sides could result.
When the Troll dies everyone near by and in the fight gets an equal share of the accumulated xp but also flagged pvp and the winner of that fight takes all the Gold.
"Tease The Troll" might the kind of fun that could attract and hold the attention of a random and changing group for many hours. A big fight with, potentially a big payoff; and ideally enough chaos to give a low level player a chance.
Might be fun from a spectators pov as well.
